It's completely uninteresting because it's an end-run around the FDA's regulations on caffeine. Let's just brainstorm all the ways to ingest caffeine, eliminate the ones the FDA has explicit regulatory power over, then target what remains.

Frankly this is really disappointing to me, it seems like Thiel is supporting people who support his libertarian views more than actual visionaries. There are lots of people who would be well served by this program, and this guy doesn't really fit the bill in my opinion. It may as well be the 'Peter Thiel drop out of school to create trouble for regulatory agencies I don't agree with' scholarship.
